Cadastre in Croatia (1)

• Established in second half of 19th century (K.u.K
  Monarchy)
• Completly established before 1914.
• Neglected in Yugoslavia, both kingdom and
  socialist era (due to different reasons)
• Taxation role canceled on January 1st 1998.
• Transfer to real-estate cadastre according
  to new law since March 1st 2000.

Cadastre in Croatia (2)

• Size 56.537 km²
• Dual system of registration (LR and C)
• 22,812 mio parcels (plots), 2,444 mio
  possesor-sheets
• 55.860 cadastal maps (1500, 1000, 2000,
  2880, 2914,25, 5760,
  5828,5)
• 100.000 changes/year
• Alpha/numerical data 100 in digital form
• Graphical data 35 rasterized,
  25 vectorised

Organisation

• State Geodetic Administration 1.400 employes,
  central, 20 regional and 92 branch offices
• Croatian Geodetic Institute quality control
• 500 licenced private surveyors and companies
• Croatian chamber of architects and ingenieurs in
  civil ingenieuring (750 members- surveyors)
• Faculty of Geodesy University of Zagreb
• Croatian Geodetic Society

8
Legal frame

• Constitution
• Law on government
• Law on Property and Law on Land Registry
• Law on State Survey and Real-estate Cadastre,
  adopted November 1999., in use March 2000.
• Supported by 12 bylaws (7 introduced, 3 in
  process, 2 remained)

Demand on digital data

• Physical planing regional 125.000, local plans
  15.000
• Water and Forestry management plans 15.000
• Agricultural land management 15.000
• Demining IT system 125.000 15.000
• Maritime domain and concesion 12.000
• Telecommunications, Electricity, Oil Gas
  Pipelines, road authorities, ...

Chalenges of digitalisation

• Cadastral topographical data will be
  digitalised with or withouth SGA!
• Speed of digitalisation is determined by users
  demand!
• Standardized multifunctional data format can
  will not be defined by users!
• Digitalisation process is limited mainly by time
  and not by the money!
• Digitalisation vs. future of NMCAs?!

11
Looking for the Croatian solution

• Reorganizing SGA and inforcing private sector in
  Croatia
• Developing a 5-years Programe with clear tasks,
  priorities, quantities and financial sources
  (interest based cofinancing)
• Investmens in basic data capture
• Participating and promoting international
  cooperation
• All activities should be driven by a clear
  vision!

12
Vision (1)

• SGA wants to be best Croatian governmental
  institution, delivering to all kind of users
  reliable, accurate and well structured digital
  informations about spatial data in Croatia.
• SGA wants to have all its data in digital form
  till 2010.!
• Promoting public-private-scientific partner-ship
  SGA wants to achieve above goal.

13
Vision (2)

• Transfering all SGAs data in to the digital form
  we aim to promote e-Croatia concept an overall
  usage of well structured (NSDI) digital data in
  (land) administration achieving
• Availability
• Managebility
• Security
• Transparency

14
Execution

• Overall umbrela Programe on State Survey and
  Real-estate Cadastre for 2001.-2005.,
  121 mio
• Real-Property Registration and Cadastre Project
  (2003.-2008.) WB,EU,RoC, 40 mio
• Bilateral projects The Netherlands, UK,
  Germany, Norway, Sweden, USA, 9 mio
• Interest based cofinancing model conuties,
  municipalities, and public enterprises 1on1

History of digitalisation of cadastral data in
Croatia

• First atempts late 70s and 80s, diverse pilot
  projects
• Vectorisation by cadastral offices late 80s and
  90s, mainly with CAD tools (Vukovar)
• Outsourcing started in 2001., defined data model
  and data structure, comparison with a/n
• Systematic vectorisation in PUK started in
  2003., scanning and vectorisation in frame of
  CRONO GIP

16
Outsourcing vectorisation model

• Participants SGA local regional authorities
• Financing model 5050
• Contractors 10 private companies
• Results in DWG files in well defined model
  corrections analysis differences analysis
  between writen vs. graphics part of cadaster

17
Inhouse vectorisation model (1)

• CRONO GIP Croatian-Norwegian Geoinformation
  Project I II
• Partners ProCaptura, PMM, SK, SGA
• Project content ProCap vectorisation software,
  Kartoscan flatbed scanner, 20 graphical
  work-stations, storage capacity, unifyed data
  base of vectorised data, vector data
  standardization and quality control interface,
  training, establishment of inland technical
  support, digitalisation management process support

18
Inhouse vectorisation model (2)

• Data model Object oriented, according to new
  digital data model of real-estate cadastre
• Key performance unifyed vectorisation procedure,
  automatized patern recognition, incorporated
  quality control procedures and tools, self
  learning software, closed and well defined
  scanning-vectorisation-saving process
• Status equipment delivered, ProCap ver. 1.2
  delivered, 5 ws operating, 15 ws in instalation

19
Scanner performance

• Cadasral maps
• 2.903 sheets in 2001.
• 3.493 sheets in 2002.
• 3.882 sheets in 2003.
• Topographical maps
• 1.800 sheets in 2002.
• 2.318 sheets in 2003.

Conclusions

• SGAs goal is to achieve level of 10.000 scanned
  and 5.000 vectorised sheets per year!
• Expect to be able achieveing it by described
  combined approach
• Inhouse capacity is crucial for controling the
  data and maintaining the necessary knowledge
  inside the SGA
• Many things should fit together to launch
  such project and execute it!
